"Model S hit a fire truck at 60mph and the driver only broke an ankle"

Tesla chief Elon Musk defended self-driving car technology on Tuesday after reports about the latest crash involving one of the electric carmaker's vehicles.

Musk lamented on Twitter about what he portrayed as an unfair focus on mishaps rather than benefits of autonomous vehicles with the potential to make roads safer.

"It's super messed up that a Tesla crash resulting in a broken ankle is front page news and the (approximately) 40,000 people who died in US auto accidents alone in past year get almost no coverage," Musk said in a tweet.

"What's actually amazing about this accident is that a Model S hit a fire truck at 60mph and the driver only broke an ankle."

Whether an Autopilot feature was engaged when a Model S collided with the rear of a stopped fire truck in the US state of Utah on May 11 remained to be confirmed.

According to local media, police said the woman at the wheel of the car claimed it was in a self-driving mode and that her attention was on her phone.

Musk complained in a recent earnings call that accidents involving self-driving cars get sensational headlines while the potential for the technology to save lives is downplayed or ignored.

Among accidents to make headlines was a fiery March 23 crash in California that involved its "Autopilot" feature.

The US National Transportation Safety Board is investigating the accident, which led to the death of a 38-year-old father of two, Walter Huang.
